Probes that can be used

General information
To measure tool and workpiece dimensions, an electronic touch-trigger probe is required that
provides a signal change (edge) when deflected with the required repeat accuracy.
The probe must operate virtually bounce-free.
Different types of probe are offered by different manufacturers.
Note
Please observe the information provided by the manufacturers of electronic probes and/or the
machine manufacturer's instructions on the following points:
● Electrical connection
● Mechanical calibration of the probe
● If a workpiece probe is used, both the direction of deflection and transmission of switching
signal to the machine column (radio, infrared or cable) must be taken into account. In some
versions, transmission is only possible in particular spindle positions or in particular ranges.
This can restrict the use of the probe.
Probes are distinguished according to the number of measuring directions.
● Multi-directional (multi probe)
● Mono-directional (mono probe)
Workpiece probe
Multi-directional (3D)
The probes also differ in the form of the stylus tip:
The measuring cycles support pin, L and star probes as autonomous tool types. The use of
the probe types is referenced in the individual measuring cycles. The multi probe is universally
applicable.
For a mono probe, the switching direction is tracked for each measurement by turning the
spindle. This can lead to a longer program runtime.
